. DETACHADEE HosEs'rIoE carin To all whom it may concern:

Be it known that I, EDWARD M. BUTLER, a citizen of the United States, residing at Groton Falls, in the-county of Westchester and State of New York, have invented a new and useful Detachable Horseshoe-Calk, of which the following is a specication.

The object of my invention isto provide an improved horseshoe calk of the detachable type which can be readily attached and which is so constructed as to remain firmly on the shoe until intentionally removed. It

is further my object to provide a device of this nature on which screw calks can be used, thus making it possible to merely replace the calks when worn without requiring a renewal of the entire device. It is an especial object of my invention to provide detachable horseshoe calks which have few parts and which are adapted to fit any ordinary plain horseshoe, in order that the device may be manufactured at small cost and be widely serviceable. I attain these and other objects of my invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a bottom plan of my invention applied to a horseshoe;

Fig. 2 is a section on line 2 2 of Fig. 1;

Fig. 3 is a top plan of my invention applied to a horseshoe; and

Fig. 4 is a side elevation of a modified form of the invention.

Like numerals designate like throughout the several views.

Referring to the accompanying drawings, I provide a plate 1 having a front extension 2, which with the lip 13 engages the inner forward portion of the horseshoe; the -plate 1 also having rear armsl 3 and 4, which with the corresponding lips 12 engage the inner rear portions of the horseshoe. As will be parts observed by referring to Fig. 1, the arm 4 is provided with a round. end portion 1'5 having a limited rotatable movement in the socket 14 of plate 1, as shown in Figs. 1 and 2. Iv provide a suitable` bolt 5 extending through the end 15 of the adjustable arm 4 and the corresponding portion of plate 1, this bolt being secured in place by a nut 6, which member has a small portion 7 adapted to seat in the slot 8 of the wedge 10. The wedge 10 is inserted under lips 11 of the arms 3 and-4, as illustrated in Figs. 2 and 3. The wedge 10 is provided with an speciation of Imefs'raten't. Pttd 001;, ggjgg.
